Application filed July 23,1923 Serial No. 653,314.

State of Massachusetts, have invented cer..

tain new and useful Improvements in Stopping ldechanism for Roving and the like Machines and I do. declare the followingv to be a fulhclear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same. 7

My invention. relates to automatic stopping mechanisms for numerous kinds of machines and, the present disclosure is directed to mechanisms of this character for use upon an American roving machine,the object being to provide an extremely simple and inexpensive,- yet an efiicient and reliable arrangement ofparts which may be easlly 1nstalled upon machines snow in use, the construction being such as to bring the usual control means of the machine into play. for stopping the latter incase of unusual movement of a selected part of the machine, such as the lower cone around which the usual belt passes. The construction herein disclosed is designed primarily'to be actuated by dropping .of the lower cone, in caset'he belt breaks.

Vit'h the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Figure 'lis a fragmentary elevation partly in section, showing the application'of'my, invention to a roving machine.

Figure 2 is a substantial duplicate of Fig.

1 with the exception that it illustrates the automatic stopping means inoperatlve posiv tion, whereas Fig. 1 discloses the relation of parts when the machine is running,

Figure 8 is a fragmentary horizontal secl tional view.

Figure 1 is an upper edge view of the actuator for the'usual knock-off lever of the roving machine.

Figure 5 is a side elevationof the actuator shown inFig. 4-.

Figure 6 is an elevation of aportion of" the releasing means for the normally idle actuator. p. i

In the drawings, above briefly. descr bed,

the numerals 1 and 2 designate thev usual upper and lo wer cones of a roving machine,

around which the well known belt 3 passes.

Belt shifting guides a are engaged with this belt and by means of a rod or the like 5 are connected with the common slidable rack 6 for moving the belt to any desired position. The usual knock-off lever or control is indicated by the numeral 7 and a horizontal latch 8 is pivoted at 9 to said lever, said latch having a shoulder 17 to engage one of the frame member 10 or other suitable part, to normally hold the lever 7 in position for runningthe machine. The latch 8 however is provided with a downturned end 11 adapted to be struck by a cam 12 on, the rack 6, when the latter is moved sufficiently in one direction, thus releasing the latch and permitting the control lever 7 to be moved in a manner to throw the machine out of operation. I

At 13, I have illustrated the usual supporting means for the lower roll 2 which in cludes the usual roll-lifting rod 14. Very often, the belt 8 breaks and permits the roll 2 to "fall, producing serious results in the machine, well known to the trade. It is the object of my invention however, to provide a novel association of parts whereby the latch 8 is automatically released and an actuator simultaneously brought into play, to shift the control lever 7 to an inoperative position, thus throwing the machine out of operation, in case the belt breaks and the cone 2 drops.

In the present. disclosure, I provide a horizontally elongated actuator 15 in the form of a metal bar, said actuator being disposed by one side of the latch '8 andfhaving a slot 16' i-n one end through which the pivot bolt or the like 9 passes for the purpose of connecting the actuator with the lever 7, yet permitting movement of said lever without moving the actuator. Near one end, the actuator 15 is providedwith' a latch portion 17 a to engagethe frame memberor the like 10 as will beclear by reference to Figs. 1 and 5, thus holding saidfactuator' against movement under the influence of the spring 18 which is connected at oneend' thereto Means are provided however, whereby the latch 8 and the actuator 15 are simultaneously released in case the cone 2 drops, thus permitting the spring 18 to come into play to shift'the knock-off or control lever 7 to the position disclosed in Fig. 2 for the pur pose of'throwing the machine out of operation.

In the preferred form o1 construction, the actuator 15 is provided with a reduced downwardly extendin end 19 whose lower extremity is bent to provide a horizontal yoke 20 which loosely surrounds the down turned end 11 of the latch 8, immediately under a pin 21 which extends laterally from said end 11. A horizontal releasing lever 22 is fulcrumed at 23 on a suitable part of the machine and one end underlies the yoke 20, while its other end is connected by a vertically adjustable rod 245 and a yoke 25, with the supporting means 13 for the lower cone By the construction and arrangement described or a substantial equivalent thereof, the controlling means of the machine, including the handle 7, is normally held in running position, by the latch 8, and the latch portion 17 of the actuator 15 then holds the latter against movement under the acti n the spring 18 but permits free movement of the lever 7 when latch 8 is reduring which movement the bolt or re 9 merely slides in the slot 16. In the belt 3 should break. however, the lower cone 2 drops, pulling downwardly upon the rod 2% and causing the lever 22 to force upwardly on the yoke 20 as disclosed in Fig. 2. This yoke strikes the pin 21 as the actuator 15 is moved upwardly and hence said actuator and the latch 8 are simultaneously released from the part 10, permitting the spring 18 to come into play and move the control means so as to stop the machine. 7 7

As excellent results may be obtained from the details disclosed, they may be followed if desired, but Within the scope of the invention as claimed, numerous minor changes may be made for adapting the invention to different types of machine.

I claim:

1. In combination, a machine having a knock-oil lever, a pivoted latch for normally iolding said lever against movement, and manually controlled means for releasing said latch from a remote point; a normally held emergency actuator for said knockoff lever movably connected with the latter to permit operation thereof independently of said actuator when said latch is released, means for automatically releasing said actuator upon unusual operation of the machine, means operated by said actuator for automatically releasing said latch when said actuator is released, and means for automatically operating said lever when said latch is released.

2. The combination with a machine having means for controlling its operation, and means for holding said control means normally against operation; of an emergency actuator for said control means normally held against movement and having a connection with said control means permi ting movement of the latter independently of the actuator, automatic releasing means for said holding means and said actuator adapted for actuation by unusual movement of a part of the machine, and means for moving said actuator when released to operate said con trolling means.
